I use 45 pistol bullets paper patched in my Marlin 1895 when I want very high velocity loads. It's not hard to hit 2400 fps with 250 grain bullets using IMR 3031. They are very accurate to 200M, but as you would expect from a pistol bullet not as good past that as a real rifle bullet. #454424 cast from pure lead at that speed is one wicked varmint load though, makes a mess of a coyote. Don't think I'd shoot anything I wanted to eat with it though.
